The Hayward Fault: 140 Years after the 1868 Hayward Earthquake
U.S. Geological Survey, California Geological Survey, Seismological Society of America
October 21, 2008, will mark the 140th Anniversary of the 1868 Hayward Earthquake, variously estimated to have had a magnitude between 6.8 and 7.0. Recent paleoseismological studies on the southern segment of the Hayward Fault suggest that the 5 most recent earthquakes on this strand of the fault have an average recurrence of 140 years: a large earthquake on the Hayward Fault tomorrow would not be a surprise. This fault poses a tremendous seismic hazard to the entire Bay Area.
This session showcases our state of knowledge of the Hayward Fault nearly 140 years after the 1868 earthquake with a focus on recent studies of the fault. Important new datasets and models include: High-resolution elevation models (from airborne LIDAR), InSAR imagery of active deformation and creep along the fault, new age dating at paleoseismic sites along the fault zone, a ShakeMap for the 1868 earthquake, 3D geometric and mechanical models of the fault, and ground motion simulations for a rupture along the Hayward Fault. We also welcome papers describing recent innovation assessments of the hazard and the risk posed by the fault, as well as new approaches for mitigating these hazards.
